B it known that I, CHARLES O. CozznNs, a citizen ofthe United States, residing at Southbridgain the county of Worcester and .State of Massachusetts, have inventedcertain new and useful Improvements in QphthalmicMountings, of which the following is a specification.

This invention relates to improvements in ophthalmic mountings and has particular referenceto that type of mounting shown in my application filed November 2 1, 1917 Serial Number 208.770, of which the present .case is a division, that being a type in which spring actuated guards are employed for retaining the mounting in position on the face; of .the' wearer, being commonly designated by the termfingerpiece mounting.

One of the principal obj ects'of the present invention is the provision ofnovel and improved construction of pivot support or hearing for a mounting of this character and of improved means for uniting the pivot connections .withthefr'ame portions of the mounting. l r A further object of the present invention is the provision of anovel and improved type of constructionin which the pivot structure an'd associated parts are enclosed or protected in place of being exposed to dirt, action of perspiration and the like, and in which the parts shall be concealed/and protected, and a more neat appearance of the mounting provided.

A further object of provision ofa novel and improved construction of mounting particularly adapted. for use in connection with what commonly termed a combination frame, thatis to say, a frame in which metallic and non-metallic parts are combined in a single mounting.

Other objects and advantages of my pres ent construction should be readily apparent by reference to the following specification taken in connection with the accompany-ing drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims Without departing from or exceeding the spirit of my invention.

Figure I represents a front view of a the invention is the.

and embodying the principles of my invention.

Figure II represents a vertical sectional view of one form thereof.

Figure III represents a similar sectional view of another form thereof.

Figure IV represents a plan view of the construction as illustrated in Figure III.

In the drawings, in which similar charactors of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the bridge or center connecting the two frame portions, each of said frame portions comprising an inner metallic portion 2 and an outer nonmetallic portion 1, the outer non-metallic frame being suitably united to the bridge 1 and to the pivot block or plate 16 as by the fastening members 3.

In thatform of my invention illustrated in Figure II of the drawings, I have shown the metallic frame 2 as split and secured. at one end to the bridge 1 and at the opposite end as carrying the block or sleeve 16. This member 16 has a central large recess 17 of sufiicient size to receive the guard or fingerpiece lever 11 with its tubular upstanding portion 10 and encircling actuating spring 12, the sleeve having arcuate slots formed at the bottom through which the lever may be operated, the parts being otherwise enformed integral with and extending upwardly from the bridge 1, while the securing screw-v14: overlies the upper portion of the post 18, the tube 10. spring 12 and member 16 hearing against the top of the member 16 to tightly clamp it against the bridge, thus uniting the ends of the frame and concealing the remaining parts, the screw extending downwardly through the post 18 and as shown into the bridge to securely lock the parts together.

In Figure III, I have shown a slightly diiferent form of the invention in that in this form the pivot is separate from in place of integral with the bridge and has a reversely extending or overhanging portion receiving the spring. In this form the pivot comprises the cylinder 21 having a lower threaded end 22 engaged in the bridge and a reversely extending spaced flange 23 providing a recess to receive the spring 12, and having a socket as at 2% to receive the projecting end of the spring, the portion 21 being provided with a shoulder 25 adapted to rest on the upper face of the lever 11, while the overhangg ingxportion 23 rests against the outer edge 01 the lever and thus forms an additional steadying member for the lever exterior to the spring 12 which is thus pactically entirely encased. In addition the portion 16 forms a sleeve or housing enclosing the post 21 and associatedparts and extends downward into tight engagement with the bridge except for the areuate slots through which the lever operates being secured in position as by the screw 1%. engaging the upper-portion oi the post. In this form of: the invention by loosening ot the screw 1a the casing 16' may be raised to open the frame for insertion or removal of a lens without in anywise disturbing the lever, pivot and actuating spring. these parts being concealed and protected even when the frame has been opened for interchangement of a lens.

From. the foregoing description talren in connection withthe accompanying drawings the construction and advantages of my improved form of mounting should be apparent and it will be seen that I have provided a novel and improved structure of combination mounting in which the metallic. and non-metallic parts of the frame are split adjacent the bridge and satis't'actorily unit-ed one with the other, and in which the pivot spring and other associated parts of the mounting for the retaining lever are associated in a neat, compact and inconspicuous manner satisfactorily protected from dirt or the like, and which. thcre'tore, provides an extremely attractive appearing mount ing, which will maintainv its appearance under roughest service conditions and at the same time give maximum amount of wear.

I claim:

1. In an eyeglass mounting the combination of a split lens enclosing ring, a nose bridge attachedto one of its ends, a sleeve attached to the other end of said ring, a

resilient fingerpiece mechanism carrying a nose grip and pivotally mounted on the bridge section of the run and pro ect1ng within said sleeve, and means for fastening the ends of said ring together.

2. In an eyeglass mounting the combination of a split. lens enclosing ring, a nose bridge attached to one of its ends, a sleeve attached to the other end of said ring, a resilient fingerpiece mechanism carrying a nose grip, a pivot stud mounted on the bridge and affording pivotal connection for said fingerpiece mechanism, and a fastening member connectihg said sleeve and pivot stud.

3. In an eyeglass mounting the combination of a split outer lens enclosing ring, an inner split lens holdingring, a nose bridge attached to one end of the inner ring, a sleeve attached to the other end thereof, a resilient fingerpiece mechanism pivotally mounted on the bridge and projecting within said sleeve, and means for fastening the ends of said rings together.

4:. In an eyeglass mounting the combination of a split outer lens enclosing ring, an inner split lens holding ring having a nose bridge secured to one end and a sleeve secured to the other .end, a resilient fingerpiece mechanism pivotally mounted insaid sleeve, a pivot stud mounted on the bridge and affordingpivotal connection for the finger piece mechanism and a screw intersectin the sleeve and pivot, substantially as and for the purpose described.

5. A combination frame including a split metallic frame member, a bridge secured to one end of said frame member, a sleeve carried by the other end of said frame member, a non-metallic frame member extending around the metallic frame member, means for uniting one end of the non-metallic frame member with the bridge and the opposite end with the sleeve, means for securing the sleeve and bridge together to unite'the parts, and a fingerpiece actuating mechanism pivoted to the bridge and con tained and concealed within the sleeve.

In testimony whereof I have a'tfixed my Ignature, in presence of two witnesses.
